Mon Feb 15, 2021 - Successful Crane Action

In the presence of rector Frau Prof. Johanna Eleonore Weber and Lord Mayor Herr Dr. Stefan Fassbinder, the 52 meter (170 ft) high truck-mounted crane hoisted the three main components of the telescope out of the observatory's dome. Several other single components followed the same path - flying ;-).


Just one day later, 10 to 20 cm (4 - 8 ") of fresh snow covered the area in and around Greifswald, Germany!


In the meantime, the disassembled telescope has safely reached the workshop of Meiling-Astro-Design where it will be investigated with professional eyes. Further details with the next monthly report.


We want to thank the University of Greifswald for ordering the H.N. Krane GmbH & Co. KG from Stralsund, Germany and for the permission to document this historic event from the air with a drone.

We want to thank the many reporters of the press & media who appeared abundantly like from the Greifswalder BLITZ (Greifswald LIGHTNING), Greifswald TV, NDR Nordmagazin & NDR Radio, Ostseewelle (Baltic Sea Wave), University of Greifswald as well as all members of the extremely busy WhatsApp Group "Observatory Greifswald DE" for their images (Jana Passehl, Markus Ludes, Mirja Freye, Sascha Meichsner, Sebastian Parg, Tobias Röwf, Uwe Meiling and Wolfgang Schmidt). This temporary list will be amended in case new items may arise. Please, send us a quick note in case somebody is missing in above mentioned list or in case you want to add an image ;-).


Herr Jörg Nitschke, Senior Vice President Brand and Communications of the Carl Zeiss AG

sends his congratulations!



We thank the Carl Zeiss AG for the 50,000 Euro large donation which brought this renovation on its way. At this points, thanks will also go out to all private donors, the members of the Observatory Greifswald Association e.V. and to the visitors of the Observatory Greifswald.

Disassembly from February 03 - 05, 2021

Report from the Observatory Greifswald, Germany - near Denmark, Sweden and Poland.


Details on General Restoration 2024, in German


Disassembly of telescope lens tube &

of centrifugal control including hoist weight.

Disassembly of optical units &

of counter weight, ca. 250 kg.

Under the skilful workmanship of Meiling-Astro-Design in Bernburg (Sachsen-Anhalt), Germany.


Thank you towards Zeppelin Rental Greifswald for providing us with the scaffolding.

Update Friday Feb 05, 2021


We are pleased about the successful disassembling of our telescope. Thank you!


On Monday, February 15th, 2021 from around 9 o'clock onward, we will see the erecting of the truck-mounted crane from Stralsund with a maximum height of 52 m (170 ft). It will be placed in the Inner Yard of the University next to the University's Main Building and in front of the old Physical Institute, provided is dry and calm. Such a truck-mounted crane was already successfully used during the repair of the sliding doors of the observatory at the beginning of the year 2020,

Afterwards, the individual components of the world's only CARL ZEISS DOUBLE TELESCOPE will lifted with care and precision out of the 6 m (20 ft) wooden observatory dome. Having arrived on the transport trailer of Meiling-Astro-Design, the components will be suitably boxed and transport locked.


Then a call will heard: "Group photo, please, wave our telescope goodbye and then the telescope will hit the road, the autobahn to be precise!" Its return is expected for autumn 2021, after a comprehensive and professional restorations in a specialized workshop.

Further information will follow as soon as available.

The alternative date for the cranage will be Tue February 16th 2021, in case of bad weather.

98 Years of Observatory Greifswald (1924 - 2022)

Science in Greifswald has started with the formation of the university in 1456.


Andreas Mayer gets appointed as professor for mathematics and astronomy at the eldest Swedish university in the year 1741. However, astronomy in Swedish Greifswald has literally taken off with the astronomers Andreas Mayer & Lambert Heinrich Röhl in 1762. They are the authors of the first scientific astronomical documents from Greifswald that have survived until today.


Proven observation venues and former observatories are: the Monastery Eldena, the Grey Monastery in today's Pomeranian State Museum, the residential building of Andreas Mayer in the Martin-Luther-Straße 10 (newly constructed in 1743) and the Powder Tower at the River Ryck (1775-1826). In January 1807, the Greifswald Observatory became French just to be turned over to Prussia in 1815. Today's observatory on top of the old Physical Institute was commissioned on July 12, 1924 thanks to the initiative of director Friedrich Krüger.


Important historical observations in Greifswald: Transits of Venus in 1761 & 1769 as well as 2004 & 2012. Observational data from the 18th century had been used in the first pan-European research project to calculate the distance Earth - Sun to ca. 150 million kilometers [93 million miles]. The scientist in this project who traveled the furthest was James Cook who discovered among others Australia.


Since July 29, 1992, the Observatory Greifswald e.V. operates, maintains and modernizes the world's only CARL ZEISS Double Telescope. The double telescope with a parallactical mounting and a mechanical centrifugal force tracking is situated in a 6 m [18 feet] wooden dome with vertical opening, comparable to the Einsteinturm (Einstein Tower) in Potsdam, Germany. The largest observatory of Federal Land Mecklenburg-Vorpommern consists of a lens telescope (200/3,000) from 1924 and a Newton mirror telescope (400/6,400) from 1935. The later one is appropriate for the photography of variable stars and was acquired for Greifswald's most famous astronomer Paul ten Bruggencate. For the direct viewing of the impressive sun eruptions (protuberances) a Quantum H-alpha-filter of The DayStar Filters Co., modernized in the year 2016, is in use during public observations. A MEADE Schmidt Cassegrain mirror telescope (200/1,260) and school telescope "Telementor" (63/840) are in operation for mobile observations.


The class astronomy is still mandatory in schools of the Federal Land Mecklenburg-Vorpommern thanks to the support and promotion of the founder of the Observatory Greifswald e.V. Prof. Holger Kersten and his colleague from Rostock Prof. Manfred Schukowski.


In the year 2001, minor planet 10114 (RZ 1992) receives the name "Greifswald" [Griffinwood] by its discoverers Lutz Schmadel from Heidelberg and Freimut Börngen from Jena. The research of Anneliese Schnell from Vienna showed that minor planet 496 (1902 KH) with the name "Gryphia" is also pointing towards the old University and Hanseatic City Greifswald at the beautiful Baltic Sea. Rephrased, Greifswald is one of the rare cities that have two minor planets!


Children and pupils who recently came into contact with the theme "Sun, Moon and Stars" are encouraged to apply for the "Manfred Schukowski Award for Astronomy" with its prize money of € 1.000.


The Observatory Greifswald e.V. wants to catch the hearts and spirits of young academics with the "Johannes Conrads Award for Astronomy & Aerospace". Its prize money is € 2.000. The last winner was Lisa Knaack from Fraunhofer IGP Rostock.


In 2017, Dietmar Fürst and his team was awarded with the lifetime achievement award, the "Mayer Röhl Honorary Award" which is worth € 555. He and his team have worked on the reconstruction of the eldest observatory in the Land Mecklenburg in Remplin near Rostock for 38 years. After more than 200 years, the broad public got the first chance to observe the sun again in the Observatory Remplin which was one of the most sophisticated in Europe in the 18/19th century.


People interested in astronomy have a chance to meet their kind in the study group astronomy of the very active association, typically on the 2nd Thursday of the month.


Largest current project: The € 200,000 General Restoration until the 100th Anniversary in the Year 2024.

A supporting membership & donations, with tax deductible donation receipts, for this charitable association are welcome! In case you want to mention us in your will, please, contact the president under: sternwarte-greifswald () - thank you! Two euro will donate one hour of joy to somebody in the future.


Today, the observatory is typically open for the broad public on each 1st & 3rd Thursday of the month.

Guided tours by appointment are available from € 40 on.


Thank you and goodbye.
